Application filed December 1,1900. Serial No. 381336. (No model.)

To a/ZZ whom t may concern:

Be it known that I, JAMES V. ALLEN, a citi- Zen of the United States,residing at Ontario, in the county of Wayne and State of New York, haveinvented a new and useful Street- Sweeper, of which the following is aspecification.

This invention relates to improvements in street-sweepers; and theobject is to provide a simple and inexpensive construction ofhand-sweeper which is effective in operation and which is practicallydust-proof, so that the sweeping is accomplished with little or noscattering of dust.

With the above object in View the invention consists in the novelfeatures of construction hereinafter fully described, particularlypointed out in the claim, and'clearly illustrated by the accompanyingrdrawings, in which-,-

Figure l is a perspective view of my improved sweeper. Fig. 2 is avertical longitudinal sectional view. Fig. 3 is a rear elevation withthe housing for the brush broken away, and Fig. 4 is a detail View ofthe gearing for the revolving brush.

Referring now more particularly to the accompanying drawings, Adesignates a frame, upon the under side of whicha transverselyextendingaxle B is mounted, said axle havingl at its respective endsground-wheels C. The frame is surrounded by a casing D, which dependstherefrom between the groundwheels. Said casing isv formed at its frontend with an opening extending down to the bottom wall thereof, andthrough this opening the removable pan E is inserted in or removed fromthe casing, the same resting on the bottom wall thereof. Said pan at itsinner end is open and extends nearly to the rear open end of the casing.As will be seen from the drawings, the axle extends transversely throughthe casing.

Secured to the rear end of the frame and depending therefrom are thearms F, which at their lower ends are curved outwardly laterally of thecasing. These arms at their upper ends are slotted to receive bolts andsecuring-nuts, so that they may be adjusted vertically and secured intheir adjustment. The lower ends of the arms support the shaft G of arotary brush H, which brush extends transversely of the casing andacross the open rear end thereof. By curving the lower ends of the armsoutwardly from the sides of the casing a brush of sufficient length toextend at its ends in line with the ground-wheel may be supportedthereby, so that said brush will sweep close to the curbing of thestreet, which would not be the case did the groundwheel project fartherfrom the sides of the casing than the ends of the brush.

One end of the brush-shaft projects from the arm in which it is mountedand carries a gear I fixed therein, while loose on said projecting endof the shaft is a wheel J, having a rim K, provided with internalgear-teeth L and external sprocket-teeth M. Mounted on a short shaftsupported by the depending arm is a pinion N, meshing with the internalgear of wheel J and with the gear I. Secured upon the axle is asprocket-wheel O, and around this sprocket and the sprocket-teeth onwheel J a sprocket-chain P passes, so that motion is communicated towheel J and from this wheel to gear I through the medium of pinion N andthe brush caused to revolve in the proper direction-that is, toward theopen end of the casing, so as to sweep the dirt thereinto.

A housing is provided for the brush, consisting of the wall Q, whichextends over the upper and rear portions of the brush, the wallR,extendin g beneath the brush, at the forward portion thereof, saidwall being attached to the bottom wall of the casing and extendingupwardly at an inclination over the edge of the removable pan, so as toconduct the dirt thereto, and the end walls S. Thus the brush isentirely incased excepting at its under side, where it engages theground.

The machine is provided with an upwardly and rearwardly extending handleT, projecting beyond the brush, so that the device may be readilyoperated to sweep the street.

The sweepings may be quickly and readily removed from the casing bywithdrawing the removable pan therefrom.

From theabove description it will be seen that I have produced a verysimple and inexpensive construction of hand-sweeper which may beconveniently operated to effect the sweeping and from which thesweepings may be quickly removed, the machine being capable of sweepingclose to the curbing of the street, and so constructed as to preventscattering of dust during the sweeping operation.

Having thus fully described my invention, what l claim as new, anddesire to secure by Letters Patent of the United States, is-

A street sweeper comprising groundwheels, a casing supported betweensaid wheels and having its rear end open and its forward end formed withan opening, a pau in said casing upon the bottom wall thereof andmovable in and out through said opening iu the forward end, armsadjustably secured to the casing at its Yrear end and iared outward fromthe sides thereof, a brush positioned at said open end and mounted insaid arms, and having its ends projecting to a point in line with theouter sides of the ground-wheels, a housing arranged at the rear end ofthe casing and entirely incasing said brush excepting at its under side,said housing having a lower wall arranged forward of lthe brush andinclined upwardly and having its upper end extending over the bottomwall of the removable pan when the same is in position in the casing,and means for imparting motion to said brush by the rotation of theground-Wheels, substantially as described.
